Cosmological parameter analyses using transversal BAO data
Rafael C. Nunes, Santosh K. Yadav, J. F. Jesus +1
We investigate observational constraints on cosmological parameters combining 15 measurements of the transversal BAO scale (obtained free of any fiducial cosmology) with Planck-CMB…
Constraints on Dark Matter-Photon Coupling in the Presence of Time-Varying Dark Energy
Santosh Kumar Yadav
In a recent work [Phys. Rev. D 98, 043521 (2018)], we have investigated a dark matter (DM)-photon coupling model in which the DM decays into photons in the presence of dark energy…
Dark sector interaction: a remedy of the tensions between CMB and LSS data
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
The well-known tensions on the cosmological parameters and within the CDM cosmology shown by the Planck-CMB and LSS data are possibly due to the systematics in the d…
Testing the warmness of dark matter
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
Dark matter (DM) as a pressureless perfect fluid provides a good fit of the standard CDM model to the astrophysical and cosmological data. In this paper, we investigate two exte…
Cosmological bounds on dark matter-photon coupling
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
We investigate an extension of the CDM model where the dark matter (DM) is coupled to photons, inducing a nonconservation of the numbers of particles for both species, where the…
A Fast Data Driven Shrinkage of Singular Values for Arbitrary Rank Signal Matrix Denoising
Santosh Kumar Yadav, Rohit Sinha, Prabin Kumar Bora
Recovering a low-rank signal matrix from its noisy observation, commonly known as matrix denoising, is a fundamental inverse problem in statistical signal processing. Matrix denois…
Electrocardiogram signal denoising using non-local wavelet transform domain filtering
Santosh Kumar Yadav, Rohit Sinha, Prabin Kumar Bora
ECG signals are usually corrupted by baseline wander, power-line interference, muscle noise, etc. and numerous methods have been proposed to remove these noises. However, in case o…
